This application is related to U.S. patent application Ser. No. 10/830,865, filed Apr. 23, 2004, entitled METHOD AND SYSTEM FOR EDITABLE WEB BROWSING, which is incorporated herein by reference in its entirety.
The described technology relates generally to browsing the web and in particular to editing web pages.
Today's computer networking environments, such as the Internet, offer mechanisms for delivering documents between heterogeneous computer systems. One such network, the World Wide Web network, which comprises a subset of Internet sites, supports a standard protocol for requesting and receiving documents known as web pages. This protocol is known as the Hypertext Transfer Protocol (“HTTP”). HTTP defines a high-level message passing protocol for sending and receiving packets of information between diverse applications. Details of HTTP can be found in various documents, including T. Berners-Lee et al., Hypertext Transfer Protocol—HTTP 1.0, Request for Comments (RFC) 1945, MIT/LCS, May 1996. Each HTTP message follows a specific layout that includes, among other information, a header that contains information specific to the request or response. Further, each HTTP request message contains a universal resource identifier (“URI”) that specifies to which network resource the request is to be applied. A URI is either a Uniform Resource Locator (“URL”) or a Uniform Resource Name (“URN”) or any other formatted string that identifies a network resource. The URI contained in a request message, in effect, identifies the destination machine for a message. URLs, as an example of URIs, are discussed in detail in T. Berners-Lee et al., Uniforn Resource Locators (URL), RVC 1738, CERN, Xerox PARC, Univ. of Minn., December 1994.
A browser application enables users to navigate among web servers on the web network by requesting and receiving web pages. For the purposes of this discussion, a web page is any type of document that can be served by a web server. These documents can be in various formats such as an HTML format, an XHTML format, a word processing format (e.g., Microsoft Word), a spreadsheet format (e.g., Microsoft Excel), a presentation format (e.g., Microsoft PowerPoint), a portable document format (e.g., Adobe PDF), and so on. The HTML format is a document markup language, defined by the Hypertext Markup Language (“HTML”) specification. HTML defines tags for specifying how to interpret the text and images stored in an HTML document. For example, there are HTML tags for defining paragraph formats and for emboldening and underlining text. In addition, the HTML format defines tags for adding images to documents and for formatting and aligning text with respect to images. HTML tags appear between angle brackets, for example, <HTML>. Further details of HTML are discussed in T. Berners-Lee and D. Connolly, Hypertext Markup Language-2.0, RFC 1866, MIT/W3C, November 1995.
A web browser application executes on a client computer, which communicates with a web server by sending and receiving HTTP messages. The web browser “navigates” to new locations on the network to browse (display) what is available at these locations. (A collection of web pages at a location (e.g., hosted by the same web server) is referred to as a “web site.”) In particular, when the web browser “navigates” to a new location, it requests a new document from the new location (e.g., the web server) by sending an HTTP request message using any well-known underlying communications protocol. The HTTP request message follows the specific layout discussed above, including a header and a URI field that specifies the network location to which to apply the request. When the web server specified by URI receives the HTTP request message, it interprets the message and sends a return message to the source location that originated the message in the form of an HTTP response message. In addition to the standard features of an HTTP message such as the header, the HTTP response message contains the requested HTML document. When the HTTP response message reaches the client computer, the web browser application extracts the HTML document from the message and parses and interprets (executes) the HTML code in the document to display the document on a display screen of the client computer as specified by the HTML tags.
The creation and maintenance of web pages can be a time-consuming task. Many tools are available to assist in the creation of web pages, which are defined by HTML documents. Web site administrators use these tools to define the layout of a web page, the content to be dynamically added to a web page, links to other web pages, and so on. When an administrator wants to modify a web page, the administrator may use the same tools to generate a revised HTML document.
Some web sites create all their HTML documents dynamically, based on content stored in a database. For example, a news web site may store all its articles in a database along with information describing the layout of each web page. When the news web site is accessed, the page layout description along with its content is retrieved from the database and an HTML document is created. These web sites may use a content management system to manage the layout description and content. Some content management systems provide special-purpose editors to assist users in managing the information stored in the database.
Although these tools for creating and maintaining web pages generally operate on offline copies of an entire web site, some of these tools allow users to browse to a live web page and select to edit that web page. Such tools are referred to as “online” editors. One browser provides an online editor that is launched in a separate window for modifying the definition of the web page currently been viewed. That editor provides a what-you-see-is-what-you-get (“WYSIWYG”) metaphor that allows images from the remote computer system to be added to the definition of the web page. When editing of the web page is complete, a user can select a publish button and enter appropriate publication information for updating the definition of the web page at the web site. The publication information may include the URL of the web page, user name and password, title of web page, and so on.
Current tools for creating and maintaining web pages have several disadvantages. First, these tools often do not provide any indication of whether a web page that is currently being displayed by a browser can be edited by the user. Thus, to find out whether a web page is editable, a user may try to edit the web page. If the web page is not editable, the user finds out when an error message is displayed. Second, these tools typically perform the editing process in a window that is separate from the window used for browsing. As such, the user is forced to shift to an editing context, rather than simply editing in a browsing context. Third, after the editing of the web page is complete, a user typically publishes the web page so that the edited web page is stored at the web site. To publish the edited web page, a user may need to use a separate tool from the browser and editor to identify which URLs are linked to which directories at the web site. Alternatively, some tools may allow a web site administrator to provide a file to a user that maps URLs to directories. After using that tool, the user enters the destination directory into a publication window of the editor so that the edited web page can be uploaded and stored at the appropriate location of the web site. It would be desirable to have a technique for editing web pages that would overcome these disadvantages.
A method and system for editing web pages is provided. In one embodiment, an editing system allows a user, when browsing the web, to select for editing a web page that is currently being viewed. When a user navigates to a web page that the user can edit, the editing system displays an appropriate indication that the page can be edited. When the user selects to edit the currently displayed web page, the editing system enters an editing mode that allows the user to edit the web page within a browsing context. When in editing mode, the editing system may enable various toolbars and buttons within the window of the browser to facilitate the editing. When the user has completed the editing of the web page, the editing system automatically updates the web page at the web site so that the updated web page can be provided when a user navigates to that web page using the editing system or a conventional browser. In this way, a user can identify whether a web page is editable before attempting to edit it, can edit a web page in a browsing context, and does not need to know web site-specific location information when saving a web page to its web site.
In one embodiment, the editing system includes a server component that executes at a server computer and a client component that executes at a client computer. The client component includes an editable web browser component that interacts with a browsing component and an editing component to allow users to browse to and edit web pages. The client component maintains an indication of which web pages users of the client computer can edit. When a server provides a requested web page to the client computer, the editable web browser component checks to see whether the user has edit rights to that web page. If so, the editable web browser component displays to the user an indication that the web page is editable and uses the browsing component to display the web page. When the user selects to edit the web page, the editable web browser component uses the editing component to control the editing of the web page within a browsing context. Before allowing the user to edit the web page, the editable web browser component notifies the server component of the server that provided the web page that the user wants to edit the web page. The server component checks whether another user is currently editing the web page. If the web page is currently being edited by another user, the server component returns an error message to the editable web browser component so that it can notify the user and stay in the browse mode. Otherwise, the server component notifies the editable web browser component that the web page can be edited. The editable web browser component requests the server component to provide a list of images that are available to be used with the web page. The editable web browser component allows the user to edit the text of the web page, to remove images from the web page, and to add images from a list of available images. The editable web browser component may allow the user to add images to and remove images from the list. When the editing is complete, the editable web browser component retrieves client-side configuration information that specifies how to save the edited web page to the web site. The client-side configuration information may include the domain URL of the web site and an update URL of an update component of the server component. The editable web browser component identifies the update URL for the domain of the edited web page from the configuration information (which identifies the server component), packages the edited web page along with any new images, and sends a request to update the edited web page to the update URL. Upon receiving the update request directed to the update URL, the server component updates that web page in accordance with the update package.
The editing system may use various techniques to ensure that only authorized users are allowed to edit web pages. The editing system may require that users authenticate to the server before editing a web page. A web site administrator can provide each user with their authentication information (e.g., user name and password). The server component may require each edit-related request (e.g., request to edit a web page and request to update a web page) to include the authentication information. Alternatively, after authenticating the user, the server could provide the client component with an authentication certificate that is included with subsequent edit-related requests for that web page. The authentication certificate could be stored in a cookie. As another alternative, after the user is authenticated, the server can establish a secure session between the server and the client computer so that all edit-related requests can be sent securely (e.g., HTTPS). To keep up-to-date with servers, the editable web browser component may periodically (e.g., each time it is started) contact each server to which it (or a user) can authenticate to and request an update of web pages that are editable. The editable web browser component can then update its client-side configuration file accordingly.
The editing system may use various techniques to provide authentication information to users. With one technique, a web site administrator provides the authentication information directly to an authorized user (e.g., via an electronic mail message). The user then supplies the authentication information to the editable web browser component for storage in a configuration file in association with the web site. With another technique, when the web site administrator adds a new authorized user, the server component creates a user-specific authentication web page with some randomly generated name or that is accessible only by the user (e.g., stored in a special directory that has an access control mechanism). That authentication web page contains information that the editable web browser component can use to automatically update the configuration file with the authentication information of the user. The web site administrator provides to the user (e.g., via an electronic mail message) a link to the authentication web page. When the server provides the authentication web page to the client computer (e.g., after the user selects the link), the editable web browser component recognizes the authentication web page (e.g., by a special HTML tag that it contains) and updates the configuration file based on information stored in the web page (e.g., identified by a special HTML tag).
In one embodiment, an authentication web page may be used to allow retrieval of arbitrary information from a server. The authentication web page may contain authentication information along with a URL to a server. When the editable web browser component (or some other system) receives an authentication web page, it can retrieve the authentication information and the URL from the web page. The component can then use the authentication information to authenticate to the server identified by the URL. The component can use the URL to request information from the server. For example, in the editable browsing context, the component may request that the server provide the identification of the editable web pages. Upon receiving the identifications, the component can store them locally. More generally, an authentication web page can be used to provide authentication information for a server to a client-side component, which can then use the authentication information to access a server. If the web page is HTML-based, then an HTML tag can be used to identify the authentication information and the URL. In this way, information can be automatically provided to a client computer when a user browses to an authentication web page.
In one embodiment, the editing system may allow web pages to be edited by anyone who can access the web pages. The server component may add authentication information to such a web page along with information describing the server component. When the editable web browser component receives such a web page, it would recognize that the web page is not identified in the configuration file as being editable. The editable web browser component would then recognize that the web page is editable by its content (e.g., by a special HTML tag that it contains) and retrieves authentication information and server information from its content. The editable web browser component can then use that information when editing the web page. Thus, a web site administrator could specify that a certain web page can be edited by anyone who has access to the web page.
One skilled in the art will appreciate that the selection of an action (e.g., to edit a web page) by a user can be performed in various ways other than by selecting buttons. For example, the editing system may provide menus of actions, may allow users to click on a web page to edit it, and so on. When the browse the web button has been selected, the editable web browser component invokes the browser plug-in to control browsing the web. When the edit this web page button is selected, the editable web browser component enters the editing mode and invokes the HTML edit control. The HTML edit control may be a conventional control provided by a provider of an HTML editor application.
Although not shown in
The editable web browser component also allows users to add new web pages to a web site. A user can select a new page option (e.g., via a menu item). The editable web browser component then prompts the user for the URL of the web page. The editable web browser component then sends an edit-related request to the server to add the web page. The user can then browse to that URL and define the contents of the web page, which may initially be blank, a copy of an existing page, or based on a default template.
The server component of the editing system includes a web engine 121, a retrieve web page component 122, a register user component 123, an authenticate user component 124, an update web page component 125, a web page store 126, a user store 127, a web page edit store 128, and a generate authentication web page component 129. The web engine receives requests to retrieve web pages, to update web pages, and to perform other tasks as described below. When a request to retrieve a web page is received, the web engine invokes the retrieve web page component to retrieve the web page from the web page store, and sends a response to the request that includes the web page. The web page edit store may contain an access control list for each web page that can be edited. The access control list identifies those users who can edit each web page. When an edit-related request is received, the web engine authenticates the user by invoking the authentication component and then invoking the edit web page component to handle the request. When the request is to update a web page, the edit web page component may update the web page store with the HTML source for the web page, and update the available images based on the information in the update package. The register user component is used by a web site administrator to maintain authentication information for the users in the user store and maintain edit rights for the users to the web pages in the web page edit store. The generate authentication web page component includes generating for a user an authentication web page that includes authentication information that is not displayed. One skilled in the art will appreciate that requests from a browser to access a web page that is editable can be handled by a web server that is not part of the editing system. When a user requests to edit a web page, the server component can receive and process the request. Thus, traffic to the server component is limited to edit-related requests, and does not include requests to access a web page.
The computing device on which the editing system is implemented may include a central processing unit, memory, input devices (e.g., keyboard and pointing devices), output devices (e.g., display devices), and storage devices (e.g., disk drives). The memory and storage devices are computer-readable media that may contain instructions that implement the editing system. In addition, the data structures and message structures may be stored or transmitted via a data transmission medium, such as a signal on a communications link. Various communications links may be used, such as the Internet, a local area network, a wide area network, or a point-to-point dial-up connection.
The editing system may be described in the general context of computer-executable instructions, such as program modules, executed by one or more computers or other devices. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Typically, the functionality of the program modules may be combined or distributed as desired in various embodiments.
One skilled in the art will appreciate that although specific embodiments of the editing system have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention. For example, the editing system may be used to edit any content that can be provided by a web server. A web server can serve web pages that include information stored in the format of a word processor, a spreadsheet program, a database program, plain text, HTML, XML/XHTML, and so on. The editable web browser component may have a separate edit control for each of these formats. Accordingly, the invention is not limited except by the appended claims.
